China Education Equipment Purchasing News: According to Beijing Secma Environmental Protection Instrument Co., Ltd., the UoW FTIR multi-element greenhouse gas analyzer developed by Wollongong University in Australia has been on the market for more than 10 years, and has been used by many users around the world. For the observation of greenhouse gases in the ambient atmosphere and background areas, and development of measurement functions other than greenhouse gases. It can be said that the technology of UoW FTIR multi-element greenhouse gas analyzer to guide the online measurement of greenhouse gases is at the forefront.
R & D and production background and advantages
The UoW FTIR multi-element greenhouse gas gas analyzer was developed by Wollongong University in Australia, produced in cooperation with ECOTECH, and provides worldwide distribution and after-sales service in accordance with ISO9001 standards. UoW FTIR multi-element greenhouse gas gas analyzer uses multiple optical paths-Fourier Infrared Transform (FTIR) spectral measurement analysis technology and high-performance infrared detection components, combined with a complete control software system, can run fully automatically, online Accurate and continuous measurement of the concentration and isotopic abundance of various greenhouse gas components in the ambient atmosphere (or other types of mixed gases), low operating cost, suitable for long-term continuous observation. You can also change the corresponding configuration according to user needs to measure other kinds of trace gases.
Comparison of greenhouse gas observation technologies
The data shows that greenhouse gas observation technology is in the process of continuous development, and the earlier observation technology is mainly non-dispersive infrared technology and chromatographic analysis technology. In recent years, FTIR measurement technology and optical cavity ring-down measurement technology have become the frontiers of on-line measurement of greenhouse gases. Both measurement technologies have their own advantages. The former chooses the mid-infrared band, which is a strong absorption region of greenhouse gases, and the Fourier transform analysis is performed by measuring the full spectrum in a wider spectrum band, which is helpful to improve the measurement accuracy and stability, but the thermal infrared light source used is not as strong Laser light source. The latter's measurement spectrum is in the near-infrared band, the absorption of greenhouse gases is weak, and the spectrum measurement range is narrow, but the latter's strong laser light source makes up for the measurement accuracy to a certain extent.
Global users include many universities
The global users of the UoW FTIR multi-element greenhouse gas analyzer currently include: Australia ’s Wollongong University, Melbourne University, Public Wealth Scientific and Industrial Research Organization (CSIRO), Science and Technology Organization (ANSTO), New Zealand ’s National Water and Atmospheric Research Institute (NIWA), Heidelberg University, Bremen University, Max Planck Institute, Germany ’s National Institute of Standards, China Meteorological Administration (CMA), etc.
